Hello VRChatters using macOS!
If you’re creating avatars or worlds on an Apple Silicon Mac, you may have encountered the error mprotect returned EACCES, or experienced an immediate crash (with SIGILL) when launching Unity.
This issue is caused by a lack of Apple Silicon support in Harmony and MonoMod, the underlying libraries used by Harmony.
I’ve been dealing with this issue for a long time, and it’s been quite frustrating.
That’s why I created a solution and published it recently.
This package patches MonoMod in HarmonyLib and replaces it with logic that supports Apple Silicon on macOS.
You can install it via VCC by adding my repository and installing “Harmony Patches for Apple Silicon (native & Rosetta)” in your project.
For technical details, please refer to the README and source code:
